	The basic idea is that in the main mungedocs we run the entirefile and create an annotated set of lines about that file. All mungers then act on a struct mungeLines instead of on a bytes array. Making use of the metadata where appropriete. Helper functions exist to make updating a 'macro block' extremely easy.
